GXH-3011Online infrared CO analyzer

one. Working principle

GXH—3011Infrared gas analyzer belongs to non dispersive spectroscopy（NDIR）The working principle of infrared gas analysis instruments is based on the selective absorption of certain gases at specific wavelengths in the infrared band, and the degree of absorption depends on the concentration of the measured gas.

2、 Application scope

GXH—3011Infrared gas analyzer for online continuous analysisCO，CO2，CH4Waiting for the measurement of a gas. The product is widely used in industrial process control such as chemical, fertilizer, petroleum, metallurgy, steel, coke, power plants, cement, ceramics, etc; It can also be used for monitoring atmospheric and pollution source emissions, agriculture, healthcare, and scientific research fields such as colleges and universities.
